Available in PDF, EPUB and Kindle. Book excerpt: Concrete pavements represent a large portion of the transportation infrastructure. While the vast majority of concrete pavements provide excellent long-term performance, a portion of these pavements have recently shown premature joint deterioration. Substantial interest has developed in understanding why premature joint deterioration is being observed in jointed portland cement concrete pavements (PCCP). While some have attributed this damage to insufficient air void systems, poor mixture design, or chemical reaction between the salt and the paste, it is the hypothesis of this work that a component of this damage can be attributed to fluid absorption at the joints. This report begins by discussing the importance of the level of concrete saturation on freeze-thaw damage. Second, this report describes the influence of deicing salt solutions on drying and wetting of concrete. Third, the report describes some observations from field studies. Fourth, the report discusses soy methyl esters polystyrene blends (SME-PS) as a potential method to extend the service life of concrete pavements by limiting the ingress of salt solutions. The report also discusses field application of the SME-PS blends for field investigation. Finally, the report discusses the development of a test to assess chloride solution ingress during temperature cycling. The aim of this work is to provide background on some aspects that can lead to joint deterioration and to provide the pavement community alternatives on how sealers and deicers may be able to be used more efficiently to reduce joint damage.
Book Synopsis Durability of Saw-Cut Joints in Plain Cement Concrete Pavements by : Javier Castro
Download or read book Durability of Saw-Cut Joints in Plain Cement Concrete Pavements written by Javier Castro and published by Joint Transportation Research Program. This book was released on 2011-12-12 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to evaluate factors influencing the durability of the joints in portland cement concrete pavement in the state of Indiana. Specifically this work evaluated the absorption of water, the absorption of deicing solutions, the relationship between the degree of saturation and concrete deterioration, and the role of Soy Mehyl Esters as a potential concrete sealant. The aforementioned items were studied in conjunction with the observation of premature joint deterioration in concrete pavements. To better understand the potential mechanisms responsible for joint deterioration, a series of mortars were tested that are consistent with the mortar fraction of concrete paving mixtures. The first portion of the work examined the role of deicing salt solutions on the wetting and drying behavior of concrete elements (this was a joint series of experiments with SPR 3093). The second portion of the work examined the concept of the degree of saturation and its relationship with freeze-thaw damage. Specifically mortars with different air contents were examined. The final portion of the work examined the potential use of penetrating concrete sealers (like soy methyl esters) to reduce water absorption and the corresponding freeze-thaw damage.
Book Synopsis Conclusions from the Investigation of Deterioration of Joints in Concrete Pavements by : Peter Taylor
Download or read book Conclusions from the Investigation of Deterioration of Joints in Concrete Pavements written by Peter Taylor and published by . This book was released on 2016 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Premature deterioration of concrete at the joints in concrete pavements and parking lots has been reported across the northern states. The distress may first appear as shadowing when microcracking near the joints traps water, or as cracks parallel to and about 1 inch from the saw cut. The distress later exhibits as a significant loss of material. Not all roadways are distressed, but the problem is common enough to warrant attention. The aim of the work being conducted under this and parallel contracts was to improve understanding of the mechanisms behind premature joint deterioration and, based on this understanding, develop training materials and guidance documents to help practitioners reduce the risk of further distress and provide guidelines for repair techniques. While work is still needed to understand all of the details of the mechanisms behind premature deterioration and the prevention of further distress, the work in this report has contributed to advancing the state of the knowledge.

Download or read book Interim Guide for Optimum Joint Performance of Concrete Pavements written by and published by . This book was released on 2011 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this guide is to help practitioners understand how to optimize concrete pavement joint performance through the identification, mitigation, and prevention of joint deterioration. It summarizes current knowledge from research and practice to help practitioners access the latest knowledge and implement proven techniques. Emphasizing that water is the common factor in most premature joint deterioration, this guide describes various types of joint deterioration that can occur. Some distresses are caused by improper joint detailing or construction, and others can be attributed to inadequate materials or proportioning. D cracking is a form of joint distress that results from the use of poor-quality aggregates. A particular focus in this guide is joint distress due to freeze-thaw action. Numerous factors are at play in the occurrence of this distress, including the increased use of a variety of deicing chemicals and application strategies. Finally, this guide provides recommendations for minimizing the potential for joint deterioration, along with recommendations for mitigation practices to slow or stop the progress of joint deterioration.

Book excerpt: The main objective of this study was to evaluate factors influencing the durability of the joints in portland cement concrete pavement in the state of Indiana. The scope of the research included the evaluation of the absorption of water in concrete, the absorption of deicing solutions in concrete, the relationship between the degree of saturation and concrete deterioration, and the role of Soy Mehyl Esters (SME) as a potential concrete sealant. The aforementioned items were studied in conjunction with the observation of premature joint deterioration in concrete pavements. Previous work by the PI identified that deteriorating joints were observed to frequently have standing water and damaged joint sealant. This work was conducted to better understand the potential mechanisms responsible for joint deterioration, a series of mortars were tested that are consistent with the mortar fraction of concrete paving mixtures. The first portion of the work examined the role of deicing salt solutions on the wetting and drying behavior of concrete elements.

Book excerpt: Distress has recently been observed in the joints of some concrete pavements, primarily in the wet-freeze states. This distress often begins in longitudinal joints, followed by transverse joints and results in the significant loss of material from the joint area. Although it may only affect approximately 10% of the concrete pavements system-wide, it greatly reduces the service life and increases maintenance costs of the pavements it effects. Primary issues that emerged from studies on this phenomenon include the importance of the timing of joint sawing, the width of the joint opening, degree of concrete or joint sealing, drainage and degree of saturation of the concrete at the joint, quality of the air void system, role of deicing chemicals, quality of curing, and the degree of restraint at the joint. Although this broad collection of issues implies that we still lack complete understanding of all causes of joint deterioration, it also makes it pretty clear that the observed damage is a result of combination of several factors. This study synthesizes completed research related to concrete pavements joint deterioration and provides information to advance the knowledge and understanding of the variables involved in in this deterioration process and suggests the best practices that can lead to its reduction or mitigation.

Book Synopsis Early Detection of Joint Distress in Portland Cement Concrete Pavements by : Dwayne Harris
Download or read book Early Detection of Joint Distress in Portland Cement Concrete Pavements written by Dwayne Harris and published by . This book was released on 2015-09-01 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: INDOT (as well as several surrounding states) have observed that certain concrete pavements may show a susceptibility to joint deterioration. Unfortunately, by the time that this joint deterioration is observed it is often too late and costly partial depth repairs are needed. The deterioration is generally occurring in the joint behind the backer rod and joint sealant; as such, it is difficult to detect even if one is standing directly above the joint. This project investigated the use of electrical resistivity and ground penetrating radar as two techniques to detect premature joint deterioration. The thought process was that if the joint deterioration is determined at an early stage, low cost corrective actions can be taken to extend the life of the concrete. The electrical response was measured for mortars subjected to a temperature cycle from 23 °C to -35 °C, with varying degrees of saturation, and varying salt concentrations. The resistivity increased as the degree of saturation was reduced due to the reduction in the volume of the conductive medium and increase in tortuosity. Changes in resistivity were detected when cracking occurred in the sample. The magnitude of these changes was similar to that detected using changes in the ultrasonic wave speed. Ground penetrating radar (GPR) was used effectively to detect fluid accumulation in the saw-cut joint behind the joint sealant. The typical GPR waveforms are however difficult and time consuming to interpret. A signal processing approach called, referred to as the CID, was used to obtain a single number that reflects the potential for fluid in the joint. Scalar waveform features and the computed CID can be used to estimate which joints may contain fluid thereby providing insights into which joint sealant sections may need to be repaired or when a sufficient number of joints may contain fluid suggesting a larger joint maintenance effort be performed to seal the joints or the concrete.

While some have attributed this damage to insufficient air void systems, poor mixture design, or chemical reaction between the salt and the paste, it is the hypothesis of this work that a component of this damage can be attributed to fluid absorption at the joints and chemical reactions between the salt and chemistry of the matrix. This paper discusses the role of soy methyl ester - polystyrene blends (SME-PS) as a potential method to extend the service life of concrete pavements by limiting the ingress of salt solutions. The report discusses field application of the SME-PS blends for field investigation in Lafayette and Fishers. Low temperature-differential scanning calorimetry (LT-DSC) techniques identified noticeable differences between plain mortar samples and mortar treated with SME-PS. The report also discusses the development of a test to assess chloride solution ingress during temperature cycling. The aim of this work is to provide background on some aspects that can lead to joint deterioration and provide early documentation showing that sealers may help to reduce the impact of deicers on joint damage, thereby extending the life of the concrete pavement. It should be noted that these sites as well as others are still ongoing and should be monitored for long term performance. Application procedure for SME-PS should follow manufacturer's recommendation.

This book was released on 1996 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal joints of concrete pavements constitute essential elements in the overall functionality and performance of the pavement system. The noticeable deterioration of these joints on some of Kansas highways lead to performing a preliminary study in order to determine the severity of the problem and analyze the design and construction issues that might have contributed to the observed damage. Data was collected from 31 sections of interstate highway in the Kansas City, Kansas metropolitan area. Parameters such as the age of the pavement and sealant, accumulated volumes of total and heavy traffic, type of joint, slab length, slab thickness, concrete strength, steel reinforcement, etc. were analyzed in relation to the observed spalling of the longitudinal joints. The variation of these parameters, with the spalling measures presented in this report, was studied.
